Referring to the drawing in detail it will be seen that the numeral 5denotes Ia car platform mounted on wheels 6 adapted to ride on rails l.The platform is provided with an oblong opening 8 with an annular ballbearing race 9 disposed thereabout. Numeral I denotes a mold base thebottom of which is provided with an yannular race il of such a size toregister with the race 9 and from the center of the bottom projects apintle I2 with oppositely ldisposed ribs I4. The pintle with its ribsextends into the oblong opening. Ball bearings l are mounted in theraces 9 and Il. Thus the base may oscillate on the platform 5 and islimited by the abutment of the ribs i4 iof the opening 8 ias vis b'e'stillustrated -re V6'. The yi;1atfflni is provided with a Eve Il'fl.

When the machine is started, it oscillates the mold and the hot metal ispoured into the mold. All the impurities are forced to the top and themachine is kept in motion until the metal is solid. in Figure 3 I haveindicated the ingot formed in the mold 43. Numeral 46 denotes the ingotand numeral 41 indicates the defect at the top thereof.

It is thought that the construction, operation,

utility and advantages of this invention will now be clearly understoodby those skilled in this art without a more detailed descriptionthereof.

The present embodiment of the invention has been described inconsiderable detail merely for the purposes of exemplication since inactual practice it attains the features of advantage enumerated asdesirable in the statement of the invention and the above description.

It will be apparent that changes in the detalls of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit and scope of the invention as hereinafterclaimed or sacricing any of its advantages.-

Having thus described my invention, what I claim as new is:

1. A machine of the class described including. a platform, a.mold-carrying base mounted on the platform for oscillatiCn thereon, ashaft, a pair ofcams mounted on the shaft and disposed in oppositedirections, connecting rods, rings on the connecting rod circumjacentthe cams, said conrnecting rods having ends terminating in pins, andsaid base having eyes to receive said pins, a pulley, a cable trainedover the pulley, a weight on one end of the cable, and means forlengaging the other end of the cable with one of the connecting rods.

2. In combination, track rails, a car movable on said track rails andincluding awheeled platform provided with an annular racein the uppersurface thereof and having an elongated opening therein centrally'of therace, a mold carrying base having a second race in the bottom surfacethereof and provided centrally of said second race with a dependingpintley received. in said opening of the platform, lugs on the pintlecoacting with walls of the opening to limit oscillation of the baseabout the vertical axisY of said pintle, ball bearings interposedbetween 'the platform and the mold base and disposed in said races, andoscillating means for the base including a connecting rod detachablyconnectedto the base and means for reciprocating said connecting rodmounted beside the track rails.

3. In combination, track rails, a car movabl on said track rails andincluding a wheeled platform, a mold-carrying base mounted on saidplatform for oscillation about its vertical axis, `and oscillating meansfor the base including a connecting rod detachably connected to the baseand means for reciprocating said connecting rod mounted beside the trackrails.

4. In combination, track rails, a car movable on said track rails andincluding a wheeled platform, a mold-carrying base mounted on saidplatform for oscillation about its vertical axis, and oscillating meansfor the base including a connecting rod detachably connected to the baseand means for reciprocating said connecting rod mounted beside the trackrails, said connecting rod being swingable upwardly when disconnectedfrom the base, and yieldable means to hold the connecting rod inupwardly swung position.

r5. In combination, track rails, a car movable on said track rails andincluding a wheeled platform, a mold-carrying base mounted on saidplatform for oscillation about its vertical axis, and oscillating meansfor the base including a connecting rod detachably connected to the baseand means for reciprocating said connecting rod mounted beside the trackrails, and manually releasable means to prevent oscillation of the baserelative to the platform. v

6. In combination, track rails, a car movable on said track rails andincluding a wheeled platform, a mold-carrying base mounted on saidplatform for oscillation about its vertical axis, and Oscillating meansfor the base including an extensible connecting rod detachably connectedto the base and means for reciprocating said connecting rod mountedbeside the track rails.
